Re: Proposing elisp-eval-target for eval-last-sexp and related commands

[Psionic K]

Indeed ielm is my workflow for this use case.  When I shared a shortcut on Reddit for the `ielm-change-working-buffer` solution, it was obvious that many users have a strong preference for working in an elisp major mode buffer.  I can't provide a shortcut however because the `eval-last-sexp` style functions don't have any `working-buffer` concept like the ielm implementation.   The change I'm proposing will allow the extremely low friction of the ielm solution but with the freedom of an elisp major mode buffer.

`M-x ielm` lets you do just that.

Having a dedicated buffer also lets it print the result more comfortably
and show the "target buffer" in the mode line.
